Having problems with your Hannstar Computer Monitors ?

HannStar HC174 LCD monitor Screen turned white for no apparent reason.After not being connected for 2months worked perfect for 4 hours hasn't worked since after shut down


Answers :

Hello,

You have a monitor with a bad power supply, it is not supplying the correct voltages to the driver board so you get a white screen. This is a very common problem with monitors that are 2 or more years old.\015\012The heat build up in the monitor case causes parts called capacitors to\015\012blow leading to the power supply short. If you can solder you should be\015\012able to do the repair. Go to our web site at:
www.ccl-la.com/badcaps.htm\015\012We have pictures of what to look for. Now take the back off of your\015\012monitor and replace all of the caps that look like the pictures and you\015\012should be back going again. Be sure to use high temp parts, they will\015\012be marked 105c. The values you will need to get will be marked on the\015\012sides of the bad ones such as 220uf, 470uf or 1000uf. When you insert\015\012the new ones be sure to put the polarity stripe going the same\015\012direction as the old one comes out. If you have any questions just let\015\012me know. If you don't want to do the repair yourself we do offer a\015\012repair service for $30 + return shipping2.gif.

I hope this helps, if so please rate our solution.
